Hello, one day I went to school with my Iphone 3g and then suddenly I take it out and it freezes, I do a DFU on the Iphone and it shuts off. After it shuts off I attempt to turn it back on, but when I tried to turn it back on the screen just stays blank (Tried to turn it on for at least 50 times.)... I have tried to check for a loose cable, but nothing is loose at all. I recently replaced the screen on the Iphone(Digitizer) and it was working when I installed it... I have tried doing a DFU, Hard Reset, Entering Recovery, Plugging it into the computer and Power Connector. I can't seem to even turn it on at all and when I do a DFU. Itunes appears and it says Capacity N/A for everything and Iphone for the Name even though I put a name on there. I can't restore it at all, I get a 1601 error. Is my phone broken, or is it just a faulty screen?
